Recent Progress of Application of DLLME to Analysis of Organic Compounds and Metal Ions

A review on the progress of application of dispersive liquid-liquid micro-extraction (DLLME) to the analysis of organic compounds and trace metal ions was given in this paper, relating especially to the topic on the principle and procedure of extraction, the influential factors of extraction, including extraction solvent, dispersing agents, concentration of chelating agents, extraction time, values of pH, salt effect and coexisting ions (42 ref. cited).
